The object of the invention is to improve a wheel spacer disc regardingthe ability to mount a rim on the wheel spacer disc, as well as the rimtogether with the wheel spacer disc on a wheel hub.

In order to achieve the object, a wheel spacer disc for motor vehicleshaving the features of claim 1, an arrangement comprising a wheel hub,the wheel spacer disc for motor vehicles and a rim as claimed in claim10 and a further arrangement comprising the wheel hub, the wheel spacerdisc for motor vehicles and the rim as claimed in claim 13 are providedaccording to the invention. Developments are specified in the dependentclaims 2 to 9, 11 to 12 and 14 to 16.

According to the invention, a wheel spacer disc for motor vehicles isprovided, said wheel spacer disc comprising a plurality of wheel boltopenings, comprising a rim centering element for centering a rimrelative to the wheel spacer disc and comprising a wheel hub centeringelement for centering the wheel spacer disc relative to a wheel hub,wherein the plurality of wheel bolt openings are designed in each caseas stepped openings for the respective partial reception of shaft nuts,wherein a section of the stepped openings having a greater diameter isarranged on a side of the wheel spacer disc on which the rim centeringelement is arranged.

A wheel spacer disc, also called a spacer disc, in the context of theinvention is a disc which serves to achieve track widening on a motorvehicle and thus an increase in the track width of the motor vehicle.The wheel spacer disc may have various embodiments. An embodiment of thewheel spacer disc in annular shape is particularly advantageous, whereinelements of the wheel spacer disc are arranged as symmetrically aspossible about a central longitudinal axis of the wheel spacer disc. Asymmetrical embodiment of the wheel spacer disc is particularlyadvantageous in terms of a mass distribution about a rotational axiswhich in an ideal case corresponds to the central longitudinal axis ofthe wheel spacer disc in order to avoid possible imbalance during arotation of the wheel spacer disc.

In a preferred embodiment, the wheel spacer disc comprises a centeropening. The center opening is to be understood as a recess whichextends along the central longitudinal axis of the wheel spacer discthrough the wheel spacer disc and may receive at least partially acentering element of the wheel hub, by the centering element of thewheel hub projecting into the center opening or penetrating through thecenter opening. The center opening is particularly advantageouslyarranged centrally on the wheel spacer disc. Moreover, the centeropening has a circumferential wall which has a height along the centrallongitudinal axis of the wheel spacer disc which in turn corresponds toa thickness of the wheel spacer disc. In one embodiment, the wheelspacer disc may have a shaping or recess which is arranged centrally onthe wheel spacer disc and which may extend along a central longitudinalaxis of the wheel spacer disc. In this case the wheel hub centeringelement may be arranged on an inner face of the shaping for centeringthe wheel spacer disc relative to the wheel hub, and the rim centeringelement may be arranged on an outer face of the shaping for centeringthe rim relative to the wheel spacer disc.

The wheel spacer disc for motor vehicles also has the plurality of wheelbolt openings, in particular five wheel bolt openings, which aredesigned as stepped openings. In particular, the wheel spacer disc hasno further wheel bolt openings or openings configured as a steppedopening for inserting bolts and the like, so that all of the wheel boltopenings are designed as stepped openings for partially receiving shaftnuts. The stepped openings serve for at least partially receiving shaftnuts. In this case the stepped openings, on the one hand, have thegreater diameter for receiving the shaft nuts and, on the other hand, asmaller diameter for receiving the stud bolts of the wheel hub. In thiscase, the section of the stepped openings having the greater diameter isarranged on the side of the wheel spacer disc on which the rim centeringelement is also arranged for centering the rim relative to the wheelspacer disc and the section of the stepped openings having the smallerdiameter is arranged on the side of the wheel spacer disc remote fromthe rim centering element. So that the section of the stepped openingshaving the greater diameter is able to receive the shaft nuts at leastpartially, the greater diameter has at least a diameter which isconfigured to be equal to or greater than the diameter of a shaft of theshaft nuts.

In a development of the invention it may be provided that the wheelspacer disc has a thickness along a central longitudinal axis of thewheel spacer disc which is less than 15 mm, in particular 2 mm, inparticular 3 mm, 5 mm, 8 mm or 10 mm, in particular is between 2 mm and15 mm.

In a development of the invention it may be provided that a section ofthe stepped openings having a smaller diameter has a thickness along thecentral longitudinal axis of the wheel spacer disc which is between 2 mmand 5 mm.

The section of the stepped openings having the smaller diameter in thiscase is designed such that it is configured to be sufficiently stable inorder to center the wheel spacer disc for motor vehicles on a plurality,of stud bolts of the wheel hub sufficiently accurately and does notexceed a thickness along the central longitudinal axis of the wheelspacer disc which could hinder the respective partial reception of theshaft nuts during a screwing-in process. Particularly advantageously,the section of the stepped openings having the smaller diameter has athickness along the central longitudinal axis of the wheel spacer discof 2 mm to 5 mm.

In a development of the invention it may be provided that the section ofthe stepped openings having the smaller diameter has at least adifference in diameter relative to the section of the stepped openingshaving the greater diameter, which corresponds to twice the wallthickness of the shaft nuts.

In order to guarantee that the shaft nuts are respectively partiallyreceived, at least one spacing which corresponds to the wall thicknessof the shaft nuts is required between a circumferential wall of thesection having the greater diameter of the stepped openings and theplurality of stud bolts. Particularly preferably, this spacing is atleast as great as the wall thickness of the shaft nuts or greater. Thespacing between the circumferential wall of the section having thegreater diameter and the plurality of stud bolts is predetermined by thesection of the stepped openings having the smaller diameter. The sectionof the stepped openings having the smaller diameter thus extends furtherinto the wheel bolt openings, at least by the difference in diameterrelative to the section of the stepped openings having the greaterdiameter, which corresponds to twice the wall thickness of the shaftnuts. Thus a partial penetration of the shaft nuts into the steppedopenings is not hindered during a mounting process.

In a development of the invention it may be provided that the rimcentering element and the wheel hub centering element are configured ineach case integrally with the wheel spacer disc.

In a preferred embodiment the rim centering element extends out of thewheel spacer disc circumferentially around the center opening. In thiscase the rim centering element also has a rim centering surface which isarranged on the rim centering element and which is arranged remote fromthe central longitudinal axis of the wheel spacer disc. Moreover, in thepreferred embodiment the wheel hub centering element is arrangedcircumferentially on the center opening and facing the centrallongitudinal axis of the wheel spacer disc. Thus in the preferredembodiment the rim centering element and the wheel hub centering elementare configured from the same material as the wheel spacer disc. Thewheel spacer disc is particularly advantageously configured fromaluminum or any other material which is relatively lightweight and yetrobust.

In a development of the invention it may be provided that the rimcentering element and the wheel hub centering element are configured asa separate component, in particular as an annular component.

A component which has the rim centering element and the wheel hubcentering element may be provided separately from the wheel spacer disc.Particularly advantageously, the separate component is designed as anannular component and is able to be inserted into the center opening ofthe wheel spacer disc. To this end, the center opening of the wheelspacer disc has a substantially greater diameter than the centeringelement of the wheel hub. The separate component is thus able to beinserted into the center opening of the wheel spacer disc. For example,the separate component is a ring which is configured from plastics andwhich is able to be fastened by means of a latching device to acircumferential wall of the center opening of the wheel spacer disc.This ring has the wheel hub centering element and the rim centeringelement. The rim centering element extends in the latched state of theseparate component in the center opening of the wheel spacer discsubstantially parallel to and along the central longitudinal axis of thewheel spacer disc away from the wheel spacer disc. Moreover, theseparate component which is shaped as a ring has the wheel hub centeringelement on an inner face. The wheel hub centering element extends alongthe separate component substantially parallel to and in the direction ofthe central longitudinal axis of the wheel spacer disc, whilst it facesthe central longitudinal axis of the wheel spacer disc. The rimcentering element is arranged, however, remote from the centrallongitudinal axis of the wheel spacer disc and extends on an outer faceof the separate component. The separate component thus serves firstlyfor centering the wheel spacer disc relative to the wheel hub andsecondly for centering the wheel spacer disc relative to the rim. Thisseparate component with the latching device, the rim centering elementand the wheel hub centering element may be configured, for example, fromplastics, a material similar to plastics or any other suitable material.In this case, the separate component has to be sufficiently stable inorder to be able to ensure the centering of the rim relative to thewheel spacer disc and the centering of the wheel spacer disc relative tothe wheel hub.

In a development of the invention it may be provided that the rimcentering element is arranged circumferentially around a center openingof the wheel spacer disc and extends out of the wheel spacer disc alongthe central longitudinal axis of the wheel spacer disc.

The rim centering element extends substantially circumferentially aroundthe center opening of the wheel spacer disc, out of said wheel spacerdisc. In this case, the rim centering surface of the rim centeringelement is oriented substantially parallel to the central longitudinalaxis of the wheel spacer disc. This rim centering surface may run in thesame direction as the rim centering element extending out of the wheelspacer disc along the central longitudinal axis of the wheel spacerdisc, conically toward the central longitudinal axis of the wheel spacerdisc. Thus it is possible to compensate for tolerances when pushing thewheel spacer disc onto the rim. This is relevant, in particular, formanufacturing tolerances which may play a role both in the rim and inthe wheel spacer disc and may be compensated by the rim centeringelement running conically toward the central longitudinal axis.

In a development of the invention it may be provided that the wheel hubcentering element is configured as a circumferential wall around thecenter opening.

Whilst the circumferential wall is oriented at least substantiallyparallel to the central longitudinal axis of the wheel spacer disc, inone embodiment the circumferential wall and thus the wheel hub centeringelement may also run slightly conically toward the central longitudinalaxis and in the same direction in which the rim centering element alsoextends out of the wheel spacer disc. Thus it is possible to compensatefor tolerances, in particular manufacturing tolerances, of the wheel huband the wheel spacer disc when pushing the wheel spacer disc onto thewheel hub and/or onto the centering element of the wheel hub. The wheelhub centering element, as a circumferential wall around the centeropening, thus tapers toward the central longitudinal axis of the wheelspacer disc in the same direction as that of the rim centering elementextending out of the wheel spacer disc.

According to the invention an arrangement comprising a wheel hub, awheel spacer disc according to the invention and a rim for motorvehicles is provided, wherein the wheel hub has at least one centeringelement and a plurality of stud bolts for fastening the rim, wherein thewheel spacer disc is centered relative to the wheel hub, wherein the rimis centered by means of the rim centering element relative to the wheelspacer disc, wherein a plurality of wheel bolt openings of the wheelspacer disc are oriented so as to be aligned with a plurality of wheelbolt openings of the rim, and the plurality of stud bolts of the wheelhub are arranged in each case at least partially in the plurality ofwheel bolt openings of the wheel spacer disc, wherein a plurality ofshaft nuts are provided for fastening the rim and the wheel spacer discto the wheel hub, wherein the plurality of shaft nuts are screwed ineach case onto the plurality of stud bolts of the wheel hub, wherein theshaft nuts project through the plurality of wheel bolt openings of therim and wherein the plurality of shaft nuts in the region of steppedopenings project at least partially into the section of the steppedopenings of the wheel spacer disc having the greater diameter.

In a mounted state, a bearing surface of the wheel hub is in abutmentwith a wheel hub bearing surface of the wheel spacer disc. Furthermore,a rim bearing surface of the wheel spacer disc is in abutment with abearing surface of the rim. The stud bolts of the wheel hub have aspecific length. The stud bolts of the wheel hub project through thewheel bolt openings of the wheel spacer disc and at least into the wheelbolt openings of the rim. With an increase in the thickness of the wheelspacer disc along the central longitudinal axis of the wheel spacerdisc, therefore, the projection of the stud bolts into the wheel boltopenings of the rim reduces. Particularly advantageously, therefore, ashaft length of the shaft nuts is dimensioned such that a sufficientthreaded engagement of the shaft nuts on the plurality of stud bolts isensured. For the sufficient threaded engagement, the shaft nuts in theregion of the shaft openings project at least partially into the sectionof the stepped openings of the wheel spacer disc which is designed withthe greater diameter.

In a development of the invention it may be provided that the shaftlength of the plurality of shaft nuts depends on a thickness of thewheel spacer disc.

A spacing of the rim from the wheel hub increases with an increasingthickness of the wheel spacer disc. Since the plurality of stud boltsare fixed to the wheel hub, with the increasing thickness these studbolts are increasingly surrounded by the wheel bolt openings of thewheel spacer disc in the direction along the central longitudinal axisof the wheel spacer disc and away from the wheel hub. So that asufficient threaded engagement of the shaft nuts on the plurality ofstud bolts is still guaranteed, the shaft length of the shaft nuts hasto be designed to be longer and thus dependent on the thickness of thewheel spacer disc.

In a development of the invention it may be provided that a step heightof the stepped bores depends on the thickness of the wheel spacer disc.

According to the invention an arrangement comprising a wheel hub, awheel spacer disc according to the invention and a rim for motorvehicles is provided, wherein the wheel hub has at least one centeringelement and has a plurality of stud bolts for fastening the rim, whereinthe wheel spacer disc is centered relative to the wheel hub, wherein therim is centered by means of the rim centering element relative to thewheel spacer disc, wherein a plurality of wheel bolt openings of thewheel spacer disc are oriented so as to be aligned with a plurality ofwheel bolt openings of the rim and the stud bolts of the wheel hub arearranged in each case at least partially in the wheel bolt openings ofthe wheel spacer disc, wherein a plurality of shaft nuts are providedfor fastening the rim and the wheel spacer disc to the wheel hub,wherein the shaft nuts are screwed in each case onto the stud bolts ofthe wheel hub, wherein the stud bolts are provided with sleeves, whereinthe sleeves project in each case into the wheel bolt openings of thewheel spacer disc from a bearing surface of the wheel hub and ensure aspacing between a lateral surface of the stud bolts from acircumferential wall of the wheel bolt openings of the wheel spacer discand wherein the shaft nuts project through the wheel bolt openings ofthe rim, wherein the shaft nuts in the region of the wheel bolt openingsproject at least partially into the wheel bolt openings of the wheelspacer disc.

In one embodiment it may be provided that each stud bolt is providedwith a sleeve. The sleeves in this case may be designed from plastics orfrom a material similar to plastics or even from any other suitablematerial. The sleeves are pushed onto the stud bolts and determine aspacing from the circumferential wall of the plurality of wheel boltopenings of the wheel spacer disc. Due to the spacing of the lateralsurface of the stud bolts from the circumferential wall of the wheelbolt openings of the wheel spacer disc it is ensured that the shaft nutsproject at least partially into the wheel bolt openings of the wheelspacer disc. The sleeves may be pushed onto the stud bolts.

In a development of the invention it may be provided that the spacingbetween the lateral surface of the plurality of stud bolts from thecircumferential wall of the plurality of wheel bolt openings correspondsat least to a wall thickness of the plurality of shaft nuts.

So that the shaft nuts, whilst they are screwed onto the stud bolts, areable to project into the wheel bolt openings of the wheel spacer disc,it has to be ensured that the spacing between the lateral surface of thestud bolts and the circumferential wall of the wheel bolt openingsduring a screwing-in process is at least as great as the wall thicknessof the shaft nuts.

In a development of the invention it may be provided that the sleeveshave in each case a thickness along the central longitudinal axis of thewheel spacer disc which is between 2 mm and 5 mm.

Particularly advantageously the sleeves have in each case a thicknessalong the central longitudinal axis of the wheel spacer disc of 2 mm to5 mm. The thickness is important, in particular, so that a centering ofthe wheel bolt openings of the wheel spacer disc onto the stud bolts andthus onto the sleeves which are pushed onto the stud bolts issuccessful.
